Category: General, Version 4.x

Yes, you can synchronize different Outlook versions with one another with SimpleSYN. Please note that certain features may have changed in different Outlook versions. For example, from Outlook 2007 on Outlook uses color categories instead of labeling. This can result in differences between the Outlook versions.

If a computer is not reachable over network or Internet, then the synchronization is carried out as soon as the computer is back in the network or online and SimpleSYN has established a connection with the SimpleSYN server.

All Outlook items that were changed or created up to that point are automatically recognized and synchronized by SimpleSYN.

Category: Operation, Version 3.5, Version 4.x

If SimpleSYN is not run on one or more computers or if the computers are not connected via local network or Internet, synchronization conflicts can occur if:

• an Outlook item is changed on multiple computers
• an Outlook item is changed on one computer and deleted on another

SimpleSYN offers you several ways of manually resolving synchronization conflicts in the user interface under the menu point “Conflicts”. The overview lists all known conflicts. Double-click on an entry and specify in the next window how SimpleSYN should resolve the conflict. Here you have a choice of:

• Use client item:
  uses the item from the client list, changes on the server computer are overwritten

• Use server item:
  uses the item from the server list, changes on the client computer are overwritten

• Copy item:
  the item is only copied and both items are saved. Please note that only the item is duplicated

• Do not synchronize:
  the item is not synchronized. Both versions of the item are saved and treated equal. Please note: If one of the items is then changed the other item will be overwritten.

If the item is deleted on one of the computers you have the option of keeping the change or deleting the item.

Alternatively, you have the option of letting SimpleSYN resolve the conflicts automatically.

Category: Operation, Version 2.0, Version 2.1, Version 3.0, Version 3.5, Version 4.x

The synchronization is not carried out in specific intervals, but rather as needed. As soon as the SimpleSYN client and SimpleSYN server have a connection the synchronization is carried out continuously and virtually in real-time.  After the initial synchronization only changes to the Outlook database are exchanged. The Outlook synchronization runs unobtrusively in the background.

It is also possible to manually synchronize single Outlook items or folders using the SimpleSYN Outlook-Add-In. Here the synchronization is also carried out as soon as SimpleSYN has established a connection.

Example: If a new e-mail is received, an existing e-mail is changed, deleted of moved, SimpleSYN will immediately synchronize this action on all computers. SimpleSYN checks if the target folder already contains the e-mail. If the e-mail does not exist it is synchronized into the folder. If the e-mail already exists it will only be synchronized if a change has occurred. If the target computer is not reachable, the e-mail is synchronized as soon as the computer establishes a connection over the local network.

The SimpleSYN Business Version, in addition to all the features of the standard version, offers:

• Synchronization over the Internet
• Filter function - for synchronizing certain Outlook items
• Windows service - start SimpleSYN automatically even if no user is logged on to Window

Category: Installation, Version 3.5, Version 4.x

SimpleSYN requires an active internet connection for its operation. The internet connection is required to connect to a central server operated by SimpleSYN. This server is used to help in the establishment of a direct connection between the SimpleSYN server and SimpleSYN client. Only data required for establishing the connection is transferred via this central server. After establishing an connection, SimpleSYN uses the best connectivity available.

If SimpleSYN Business is used to synchronize via the Internet and it is impossible to create a direct connection between SimpleSYN server and SimpleSYN client, e.g. because of Firewalls NAT or Routers are blocking the direct connection, SimpleSYN uses a relay server as a last resort. This relay server allows SimpleSYN to communicate even if only outgoing traffic is allowed from your networks.

In either case the connection between SimpleSYN will always  use an SSL/TLS encryption respectively.

Your Outlook data is never transferred in clear-text nor stored permanently on our Internet servers (no Cloud).

Note: Proxy-Servers are not supported by SimpleSYN. SimpleSYN must communicate with our servers located at services.simplesyn.net.

SimpleSYN requires the following outbound TCP connections:

Duplicate e-mails can occur on an POP3 account, when e-mails from more than one computer being synchronized are requested from the e-mail server. This is the case if the Outlook function “Leave copy of messages on the server” was activated in a POP3 E-mail account.

The tricky here is that SimpleSYN cannot force Outlook to stop downloading an email a second time on another computer. If the first computer downloads the mail from the email server and it gets synchronized before the second computer downloads it, Outlook cannot detect that the email is already there. The second computer will than download the email from the email server and you got a duplicate. As the first email is also already synchronized, SimpleSYN assumes that the second download is intentional and synchronizes this copy too.

In this case deactivate the Outlook function “Leave copy of messages on the server” so as not to save e-mails in your mail server and download them repeatedly.

To deactivate this function follow these steps:

Outlook 2007

1. Open Outlook
2. In the menu “Tools” click on “Account Settings“
3. Highlight the POP3 E-mail account in question and click on “Change“
4. Click on “More Settings“
5. In the tab “Advanced” deactivate the check box “Leave copy of messages on the server“
6. Confirm the changes by clicking “OK“
7. Click on “Next“ and then on “Finish“

Outlook 2010, Outlook 2013 or Outlook 2016

1. Open Outlook
2. Open the Backstage area by clicking on “File“
3. In the category “Information” click on “Account Settings” and “Add or Remove Accounts…”
4. Highlight the POP3 E-mail account in question and click on “Change“
5. Click on “More Settings“
6. In the tab “Advanced” deactivate the check box “Leave copy of messages on the server“
7. Confirm the changes by clicking “OK“
8. Click on “Next“ and then on “Finish“

Provided you have made changes to the default settings of the color categories, you will have to manually set up the list of color categories (formerly main category list) identically on all computers.

You should not synchronize IMAP email folders with SimpleSYN. IMAP folders are server based and automatically synchronized on all your computers. If you synchronize the same folders with SimpleSYN, it can lead to duplicated mails because two synchronization methods are interfering.

As IMAP cannot be used to synchronize appointments, tasks, contacts and notes, it is safe to synchronize those items with SimpleSYN.

Therefore make sure no email folders (i.e inbox) are selected on the SimpleSYN client in the “synchronization settings”. Also make sure no more email folders are listed in “Status -> pending synchronization”. If there is a folder listed here, right-click it and click “Do not synchronize”.

Category: General, Version 3.0, Version 3.5, Version 4.x
